Specification of Letters Patent.

Application filed February Q7, 1914. Serial lio.821,606.

To all whom it may concern Be it known that I, PAUL Knorr, a SllbJQCt ofthe King of Saxony, residing at 3 Miinchnerstrasse, Dresden, Germany,have invented new and useful Improvements in Separators, of which thefollowing is a specification.

This invention relates to apparatus for purifying water. or otherliquids by separating therefrom solid impurities c-ontalned 1nsuspension inthe liquid, and has for its object to provide an improvedapparatus of this character which shall be slmple and cheap tomanufacture and efficient and reliable in operation.

The said invention consists in. the construction and combination ofparts hereinafter more particularly set forth and claimed, the sameconstituting a separator of solid substances from liquid, operating bycausing the liquid to change its direction of flow suddenly andrepeatedly by encountering solid parts of the separator, the suspendedsolid matter being thereby precipitated in agglomerated masses and theliquid being purified accordingly.

The accompanying drawing represents a vertical central section of aseparator cmbodying my invention.

As shown in said drawing, the separator comprises a conical tank 1providedat its base with a chamber in which the impurities arecollected. The upperand outer edge of the tank 1 is provided with anannular channel 3 communicating above its innerarranged below thebattles 5.

Centrally arranged within the upper portion of the separating member isa receiving chamber 7 into which the inlet pipe 8 of the apparatusprojects, the purified liquid being drawn oif from the channel 3 bymeans of outlet pipes 9. Said receiving chamber extends verticallydownward below the baffles and is open at the top only. Its side wallconstitutes an additional deflecting agent for the liquid. The upperbattle approaches in form an ogee curve and presents upward a shallowbroad annular trough or depression consisting of the outer portion ofsaid deflector. The lower deflector is apbaiile, which makes theexterior wall of said annular depression, up under the over hanging edgeof the lower battle, then sweeps around the inner face of the lowerbathe in a curved downwardly and inwardly directed course and isprojected by the raised inner edge thereof obliquely upward and inwardagainst the wall of said receiving chamber necessarily eddying more orless in the space immediately surrounding said receiving chamber andabove the lower part of said lower bafile, escaping at last intofunnel-form member 6 through the opening between said receiving chamberand said lower edge.

The operation of thisform of separator will be evident from aninspection of the drawing, the direction of flow of the liquid beingindicated by the arrows. seen that the liquid to be purified firstenters the chamber 7 and passes therefrom to the baffles 5. The liquidafter leaving the battles, impinges against the outer surface of thechamber 7, as above stated, and'passes downward through the funnelmember 6. The passage of the liquid through the baffies and its impacton the outer surface of the chamber 7 causes the suspended particles tobecome-massed together in larger clusters or groups which, owing totheir relatively high specific gravity, fall grad ually downward intothe collecting chamber 2, the liquid, after leaving the funnel member 6,moving in an upward direction and passing, freed from its suspendedimpurities into the channel 3 from which it is withdrawn and utilized.

I claim I 1. In combination with a collecting chamber for solid matterand a receiving chamber for liquid arranged above the same and open atthe top means for directing the overflow liquid of the latter chamber totheformer chamber and bafiles interposed in its passage, the said liquidreceiving chamber being extended downward below the lower baffle andarranged to be struck by the water It will be directed inward thereby soas to change again suddenly the direction of the flow.

2. In combination with a collecting chamber for solid matter and areceiving chamber for liquid arranged above the same means for directingoverflow liquid from the latter chamber to the former chamber andbafiies interposed in the path of flow of the liquid to change itsdirection the lower edge of the lower bafiie being inclined upward andinward to direct the liquid against said receiving chamber which isextended down far enough to receive such impact.

3. In combination with a collecting chamber for solid matter and areceiving chamber for liquid arranged above the same,

means for directing overflow liquid from the latter chamber to theformer chamber and a pair of annular bafiles arranged around saidreceiving chamber the inner and upper battle forming a shallow troughand the outer and lower battle being of scroll form and presentlng itsupper edge downward toward said trough, which it overhangs,

and its lower edge obliquely upward andv inward.

4. In combination with a funnel form part having at its upper end anannular liquid channel and outlet and at its lower end a collectingchamber for solid matter, an inner funnel form part discharging into theone first mentioned, a receiving chamber overflowing into said innerfunnel-form part and a pair of annular curved baffles surrounding saidreceiving chamber, one of said baffles at its upper edge over hangingthe other baiile and also presenting its inner and lower edge obliquelyupward toward said receiving chamber substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

PAUL KROPP.
